Hey guys I'm putting everything back together after a heater core replacement and I can't for the life of me remember where this plug attaches near the steering column. I think I'm missing something obvious here...

if anyone could help me out it would be greatly appreciated

 

So there was a very hard to see part number on it. Looked it up and it's the brake light switch. It must have popped out when I pulled the dash. Snapped right back in!
